Specification of Letters Patent.

Application filed March 28. 1503. Serial F0. 150031- To all 'ZIEIZOITI- it may concern:

Be it known that I, GEORGE W. Doxmxo, a citizen of the United Stateswesiding at East Orange, in the countvof Essex and State of New Jersey, have invented certain new and useful Improvements in Electrical 1 Type-Writers; and I do hereby declare the following to be a full, clear, and exact description of the lIlVOllUOIl, such as will enable between the key-board and the movable writing mechanism.

A further object of this invention is to obviate the use of a movable key board which necessitates reaching by the operator i over all points of the platen.

With these objects in view, and others, my invention comprehends the construction, arrangement, and combination of parts hereinafter set forth. with reference to the draws, and then pointed out in the claims.

n the drawings, representing an apparatus embodying my invention: Figure 1 is a pers ective. view; Fig. 2 is a front elevation;

ig. 3 is a rear elevation: Fig. 4 is .a side elcvation; Fig. 5 is a view in plan; and Fig 6 is a detail of the type-bar and operating magnet. Fig. 7'is a fragmentary view, partly in section, of the key-device and an underlying terminal-device.

I have referably illustrated my invent-ion as applie to a machine for writing 11 on a continuous orloose sheet or page of a boo laid on a flat surface or platen, but it will be easily understood that the paper may be fed over or around a cylindrica platen, adapted to rotate contiguous 'to the writing mechanism, and successively bring the several lines of the receiving paper into position to be printed upon.

In the. several views, in which the characters of reference indicate the same parts:

Upon the table A are mounted the track-rails B, and the lat platen (,such as are employed in what are known as b0ok-typewriters, or flat platen commercial typewriters. The

Patented Feb. 18,1908.

track-frame may be hinged at a to the base'i and thus be tiltabledf desired. The carriageframe D is preferably slidable along the rails B and supports a writing-mechanism-carriage d movable transversely thereon to efi'ect letter-spacing, as is customary in this class of machines, where the work, the book, or sheets are held stationary on the normally-stationary platen.

As shown, the track-frame extends some distance to the rear of hingeoint a so that, when the carriage-frame an its supported writing-mechanism-carriage are disposed beyond the hingeqioint, the Weight of theseparts will, when the track-frame is released at the front, tend to tilt-the forward portion of the track-frame.

The writing-mechanism on the carriage comprises the. type-bars that, when operated, print the characters on the work placed on the platen, while the keys are dis osedin frame-tie-bar-supporting member f extend-' in along the rear of the track-frame. or ta le; or siin ly a round roller may he used, from which t e member F extends to and is connected with the carriage. It is necessary to have the member F oi such length as to permit the full traverse of the carriage-frame to the front of the platen, or to a position nearest the operator, as well as to permit of the transverse movement of the carriage. To take up slack in the flexible member'and ,a stationarv bank E preferably at t e front preferably arprevent it falling upon the platen or work, I

provide a underneat able weight f. If preferred, a spring, or other device, may be used to keep the cable a taut.

If preferred, a block f may slide on the tie-barf and carry a bearing member ulley f, riding on the member F ii the table, and carrying a suit-J- has one end attached to the armature h and type bar tostrike the platen. And, when it e to efiect etter and line spacing.

its other end pivoted to a link it, the latter beingpreferably pivoted to the lower end of the type-bar H. When a current is passed through the electro-magnet, it attracts thearmature and, through the lever, causes the circuit is broken, a retractile spri h returns the type-bars and armature to air normal positions. I

The :eys K are movably disposed in the Stationary key-board E, and, when dc pressed, efiect contact between subjacent electrical terminals 1:, k, which, as shown in Figs. 4 and 7, are arranged independent of the movable key, though in the path of movement of the key.

The cable F is preferably composed of a number of insulated, flexible conductors, that form a circuit from each of the electrom eta h to an appropriate key-terminal l: and which circuits each include a suit able source of electricity, such as a battery L. Consequently, when any one of the ke s is depressed, a circuit will be com eted through one of the electro-magnets h and the type-bar corresponding to the key will be operated. And the flexible cable Fwill permit of'the operation of the type-bars by the kc s, whatever be the positionof the carriage ame.

Any a propriate means may be-ernployed From the above, it will be seen that the operator does not have to move the hands to follow the traverse of the carriage and typebars across the platen, nor to move them to different ositions along the platen to accommodate or the line-spaci as is necessary where the keys are locate on the movable carria e and carriage-frame, and hence are Shiite both longitudinally and transversely to follow the printed space on the work.

Without limiting myself to the construction and arrangement licreinbefore set forth, what I claim as new and desire to secure by Letters Patent is:
